To all whomz't may concern k:

Be it known that I, CHARLES SCHMIDT, a citizenv of the United States, residing at Milwaukee, county vof Milwa'i'ikee and State of Wisconsin, have inventedhew and useful Improvements in Lanterh- Chimneys, ofV

which the following is a specification.

The object of my invention is to provide v ing my invention. Fig. 2 is 'a plan view of' the same. j

Like parts are identified bythe same reference Characters throughout both views.

My improved chimney is formed in two members. The member A is substantially the same in contour as the smallv size glass chimneys used inordinary lanterns, except that at the lower end it is'provided with a shoulder B adapted to form arest and a notch C, the base of which is also adapted to form a rest, whereby the chimney may be fitted to supporting rings of two different diameters. At its upper end the chimney A is provided with an annular shoulder E, adapted to receive a chimney holding ring such as all ordinary lantern frames carry. The upper margin of the chimney comprises the flange F, which is adapted to project loosely through a holding ring of the smaller size. The member A is therefore adapted to fit a lantern of small size, the chimney supporting member of which will engage in the annular notch C and the holding rings of which will bear upon the annular shoulder E.

The larger lanterns are made to receive chimneys of larger diameter than the upper ends of the member A. All of the larger size lanterns receive chimneys of the larger diameter7 but different lanterns are constructed to receive chimneys which differ in height from those used in other lanterns, and' I therefore provide the neck a. of the member A with a screw thread d on its outer face, which receives the threaded inner face of an extension ring G. The extension ring G is provided with an annular shouling 1n. function with the shoulder E andA flange F on the member A, but having the required' larger diameter in order that the claming rings of the larger lanterns may bear upon the shoulder E and encircle the flange F. By screwing the extension ring G upwardly or downwardly upon the neck a, the height of the Chimney may be regulated to suit the requirement-s of any lantern of standard type, and in view of the fact that lantern chimneys are mad-e in only two diameters at the upper and lower bearing margins, it is obvious that my improved chimney may be fitted to any lantern of ordinary standard size and type.

The chimney supporting member of the larger sized lanterns will receive the annular shoulder or rest B and the chimney holding ring will bear upon the annular shoulder E but it will be observed that my improved chimney may also be applied to a lantern of the larger size, even though the supporting member may be of the same diam-V eter as a lantern of the smaller size, since the supporting member may be received in the annular recess or notch C. When my improved lantern chimney is used in a lantern of the smallest size, the ring G may be either wholly removed or it may be screwed down upon the neck a until the upper eX- tremity of the member A is exposed above the adjustable ring G. The ring G may be formed of any suitable material.

I claim- 1. A lantern chimney provided with a plurality of rests of differing diameters at its lower end, and a plurality of ring receiving members of different diameters at its upper end portion.

2. A lantern chimney provided with a plurality of rests of'differing diameter at its lower end, and a plurality of ring receiving members of dierent diameters at its upper end portion, one of said ring receiving members being adjustable with reference to the other.

3. A lantern chimney member provided with a screw threaded upper portion and an extension member adjustable thereon,

lsaid chimney and also the extension member being adapted to be engaged by a ohim- In testimony whereof I afiix 'my` signature ney holder. in the presence of two Witnesses.

fl. A lantern chimney having its upper V end portion provided With a plurality of Y Y CHARLES SCHMIDT 5 holder engaging members of different diam- `r Witnesses: y;

eters, said members, being relatively adjust- K LEvERE'i'r C. WHEELER, able vertically. v IRMA D. BREMER.
